I know that art is in the eye of the beholder, but I find this nothing short of disturbing! I would not want any of my children to go there under any circumstances. Why a photo of a boy near the cage (if you look closely he doesn't appear to be having a very good time)? Isn't the idea of a pizza party supposed to be fun? I've also seen videos about the tunnels you spoke of. They were being worked on outside the normal protocols of city inspections. Having a good deal of experience in construction, Its my experience that they are trying to hide something...not up to code or something worse.
